How To Care For String Of Fishhooks


String of Fishhooks, scientifically known as Senecio radicans, is a member of the enchanting family of String of Things succulents, a group of beloved trailing houseplants that have captured the hearts of plant enthusiasts worldwide. Alongside its botanical companions like String of Hearts (Ceropegia woodii) and String of Bananas (Senecio radicans), String of Fishhooks is a wonderful plant in this succulent lineage, renowned for its cascading vines and distinctive leaf formations.

The name "String of Fishhooks" comes from the plant's intriguing leaf shape, resembling tiny fishing hooks dangling along the cascading stems. Cultivated for its ornamental appeal and ease of care, this succulent has found its way into the hearts and homes of many due to its charming appearance and low-maintenance nature. String of Fishhooks is a resilient choice for various indoor environments. Its trailing nature makes it suitable for hanging baskets or elevated spots, allowing the vines to cascade gracefully. With its ability to withstand periods of drought, it's an excellent option for those seeking an easy-care addition to their plant collection.

While this plant is very easy and does not require advanced gardening skills, but understanding its specific requirements is crucial for maintaining your plant’s health and deciding if it's suitable for your living or working space. With the right care, you can enjoy this trailing beauty for years to come. 

String of Fishhooks vs String of Bananas

String of Fishhooks and String of Bananas are often confused with each other. Both plants are called Senecio radicans and have quite similar appearances. However, there are some key differences between the two plants that can help you distinguish them.

The most obvious difference between the two plants is their leaf shape. String of Fishhooks has slender, cylindrical leaves that resemble tiny fishhooks, while String of Bananas has elongated, bead-like leaves that resemble miniature bananas. String of Fishhooks boasts thicker, succulent leaves with a bluish-grey hue, while String of Bananas features thinner, bright green leaves.

Moreover, they have different growth habits. The string of fishhooks grows in a cascading manner, draping gracefully from hanging baskets or trailing along shelves. The string of bananas tends to grow in an upright manner, often climbing structures like trellises or string supports.

In terms of care, both plants require moderate watering, but String of Fishhooks is slightly more drought tolerant and can tolerate a bit lower light than String of Bananas. 

[Toxicity] Is String of Fishooks toxic?

General Care


String of Fishhooks thrives in bright, indirect light. While it can tolerate some direct sunlight, it's essential to strike a balance to prevent potential leaf burn or discoloration. Ideally, position your String of Fishhooks in a location with filtered sunlight or partial shade. Indoor spaces with ample but indirect light, like near a south or west-facing window, are generally optimal for its growth. It's important to monitor the plant's response to light conditions and make adjustments to its placement accordingly, ensuring it receives the right amount of light for healthy and vibrant development. Comparing to other succulents, String of Fishhooks can tolerate bit of lower lighting condition, but too little light may lead to leggy and stunted growth. 


As a succulent, String of Fishhooks is drought tolerant because it can store water in its foliage. Overwatering can lead to issues such as root rot, so it's crucial to avoid waterlogged conditions. When watering, make sure to thoroughly moisten the soil, and then let it dry out partially before the next watering. It's advisable to adjust the frequency based on factors such as the environmental conditions, the size of the pot, and the specific needs of your plant. Observing the plant's response to watering and adjusting your watering routine accordingly will contribute to a healthy and thriving String of Fishhooks.

Soil And Fertilizer

String of Fishhooks, belonging to the Senecio family, thrives best in well-draining, airy soil. You can choose a high-quality ready-made cactus or succulent mix or make your own soil using potting soil, perlite, and coarse sand. This blend ensures proper drainage, preventing waterlogged conditions that can lead to root rot. Perlite and coarse sand also promote air circulation around the roots, enhancing root health. If you notice that the soil has become compacted over time, gently loosen it with a fork or stick. Be careful not to damage the roots while doing so.

In terms of fertilization, String of Fishhooks does not demand frequent feeding. During the growing season in spring and summer, a balanced liquid fertilizer diluted to half the recommended strength can be applied every 4-6 weeks. However, it's essential to refrain from fertilizing during the dormant period in fall and winter. Over-fertilizing can lead to salt buildup in the soil, potentially harming the plant. String of Fishhooks' minimal nutritional needs make it a low-maintenance choice for those seeking an easy-to-care-for trailing succulent.

Temperature and Humidity

String of Fishhooks generally prefers temperatures between 60°F to 75°F. It is well-suited for normal room temperatures found in most homes. Ensure that the plant is protected from extreme temperature fluctuations. Make sure you do not place this plant near heating vents, fireplaces, and drafty windows. 

In terms of humidity, String of Fishhooks is adaptable to typical indoor humidity levels (30-50%). It enjoys humid rooms (humidity level of around 50%), but it doesn't require high humidity levels to thrive, and that is why this plant is super easy-care and well-suited for indoor environments. Don’t forget to provide adequate ventilation to prevent excessive humidity around the plant, as overly damp conditions may lead to issues such as root rot and mold. Good airflow is important for this plant’s healthy growth. If your room is extremely dry, especially during the winter, you can use a humidifier to improve the humidity. 


String of Fishhooks is not known to go through a true dormancy period like some other succulents. However, during the winter months, when daylight hours decrease and temperatures may be lower, the plant may slow down its growth. This is a natural response to the changing environmental conditions.


During this period, it's advisable to adjust your care routine. Reduce watering frequency as the plant's water requirements decrease with reduced growth. Be attentive to changes in the soil's moisture level, allowing the top inch of the soil to dry out before watering. With proper care, your String of Fishhooks will emerge from dormancy in the spring and resume its normal growth patterns.

Potting and Repotting

  • Choosing a Pot: Select a pot with drainage holes to prevent waterlogging. String of Fishhooks prefers slightly snug conditions, so choose a pot that accommodates its current size with a little room for growth.
  • Repotting Frequency: These succulents don't require frequent repotting and generally prefer to be a bit root-bound. Repot when you notice the plant becoming too crowded in its current container, typically every 2-3 years.
  • Repotting Process:Water the plant a day or two before repotting to make the soil softer. Next, gently remove the plant from its current pot, being careful not to damage the stems or roots. Shake off excess soil and inspect the roots. Trim any dead or rotting roots and place the plant in the center of the new pot and fill in with fresh soil around the sides. Water lightly after repotting and allow the plant to adjust to its new environment.
  • After Repotting Care: After repotting, avoid direct sunlight for a few days to allow the plant to recover. Resume regular care once the plant shows signs of acclimating to its new pot.

Pruning And Shaping

Pruning your String of Fishhooks is an easy way to keep it looking nice and encourage healthy growth. Inspect your plant regularly and trim away any yellowing or dead parts using clean scissors or pruning shears. If your plant is getting too long or looks a bit sparse, you can trim some stems just above a set of leaves to control its length and make it bushier. This is an effective method to solve leggy growth. 

You can also shape your plant by trimming where needed for a fuller look. Don’t forget to use cut stems for propagation. It is not necessary to prune regularly, only remove unwanted parts when your plant needs a little tidy-up or if you want to change its shape. Don’t over prune and remember to use clean tools. 


As with other trailing succulents, propagation String of Fishhooks is easy with stem cuttings. Follow these simple steps:

  • Select Healthy Cuttings: Choose a healthy stem from your existing plant, ensuring it's a few inches long with several sets of leaves.
  • Prepare the Cuttings: Use clean, sharp scissors or pruning shears to cut the selected stem just below a set of leaves. You can take multiple cuttings for propagating several new plants. Place the cuttings in a dry, shaded area for a day or two, allowing the cut ends to callus and prevent rotting during planting.
  • Planting the Cuttings: After callusing, plant the cuttings in well-draining succulent or cactus mix, burying the cut end just deep enough to anchor the cutting.
  • Rooting Process: Water the soil lightly and let it dry between waterings. Over the next few weeks, the cuttings will gradually develop roots. Place the planted cuttings in a location with bright, indirect light, avoiding direct sunlight that might be too intense for developing roots.
  • Transplanting: Once the cuttings have established roots and grown into small plants, transplant them into individual pots or directly into your garden if the climate is suitable. 

Common Problems

While String of Fishhooks  is generally an easy-to-care-for succulent, it may encounter a few common issues that, with attention and care, can be managed effectively:

  1. Overwatering: One of the most common problems is overwatering. String of Fishhooks prefers well-draining soil, and waterlogged conditions can lead to root rot. Allow the soil to dry out between waterings, and ensure the pot has drainage holes.
  2. Insufficient Light: String of Fishhooks thrives in bright, indirect light. If it doesn't receive enough light, it may become leggy or exhibit stretched growth. Provide ample sunlight, but avoid direct, harsh sunlight.
  3. Pests: While String of Fishhooks is relatively resistant to pests, occasionally, it may attract spider mites or mealybugs. Inspect your plant regularly, and if pests are detected, treat them promptly with insecticidal soap or neem oil.
  4. Drooping Leaves: Drooping leaves can be a sign of underwatering. Adjust your watering routine, making sure to water the plant thoroughly when the top inch of soil is dry.
  5. Yellowing Leaves: Yellowing leaves may indicate various issues, including overwatering, underwatering, or nutrient deficiencies. Evaluate your care routine and adjust accordingly.
  6. Root Rot: If the plant is overwatered consistently, it may develop root rot. To address this, allow the soil to dry out, trim away affected roots, and repot the plant in fresh, well-draining soil.
  7. Lack of Air Circulation: Similar to other trailing succulents, String of Fishhooks benefits from good air circulation. Stagnant air can contribute to fungal issues. Ensure proper spacing between plants and introduce gentle air movement if needed.
